Computer won't boot, bootmgr and checksum apparently have problems

Hi, I am experiencing issues with my computer. And my brain is bleeding, it hurts.

I am on a Windows 7 laptop. The sticker says "G61-304NR Notebook."

As of now: I can't boot the computer. When I turn it on, it goes to a hp screen (like it usually does), goes black, and then displays either "BOOTMGR Image is corrupt. The system cannot boot." or another message about something about checksum possibly being corrupted (I can't remember the exact words at the moment--only the bootmgr one is showing up right now). And then it stays like that, and I am forced to turn off the computer again because no other keys work. I've tried going into safe mode (clickclickclicking F8), but it doesn't work.
When these two messages first began appearing, I managed to start my computer properly once and I went and tried system restore. It started, but then this blue screen of death came up. Then I shut the computer down.

Before the above started happening, I was searching around on surfing the net, looking for free downloads of files, etc.
I do remember that at one point during the day, the entire screen refreshed and it looked different (the - and box and x in the top right-corner of the windows turned into something like this (link)). But then a little while afterwards, it returned to the normal look (link. I don't know if this has anything to do with it, but it scared me.
Also, I think I had the google redeirect virus but didn't do anything about it, because I thought I could deal with it later.
ALSO, when I start firefox and went to click a search on google, it wouldn't load and I would get a popup box that said "proc:click" and a lot of other gibberish I couldn't understand (but I do remember finding the url that I was trying to get to amongst the nonsense).
ALSOOO, I continuously ran the Malwarebyte's program on a full scan to try and get rid of the google redirect virus and proc:click on firefox. On the last try, it froze (it had never done this before) and I had to shut down the computer. (And then the Bootmgr&checksum messages began appearing.)
That's all I can remember doing that might have affected my computer like this. Oh--and I installed and attempted to run Combofix to get rid of the google redirect virus, but I had no idea what I was doing and probably didn't run it properly.

Thanks so much for reading this.. any ideas?
I am completely clueless, but threads in the forum have helped me in the past with viruses, and I think it's great. Again, thank you thank you. :)

ComboFix is a tool that should only be run under the supervision of someone who has been trained in its use. Using it on your own can cause problems with your computer.

Let's start here please.
Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!
Be sure to download TDSSKiller.exe (v2.4.0.0) from Kaspersky's website and not TDSSKiller.zip which appears to be an older version 2.3.2.2 of the tool.
  • Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
    Vista/Windows 7 users right-click and select Run As Administrator.
  • If TDSSKiller does not run, try renaming it.
  • To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to How to change the file extension.
  • Click the Start Scan button.
  • Do not use the computer during the scan
  • If the scan completes with nothing found, click Close to exit.
  • If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
  • Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.
  • A log file named TDSSKiller_version_date_time_log.txt (i.e. TDSSKiller.2.4.0.0_27.07.2010_09.o7.26_log.txt) will be created and saved to the root directory (usually Local Disk C:).
  • Copy and paste the contents of that file in your next reply.


If TDSSKiller does not run, try renaming it. To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to these[/color] instructions. In some cases it may be necessary to redownload TDSSKiller and randomly rename it before downloading and saving to the computer.

Sorry--when I turn my computer on, it never gets to the login screen, so I can't run anything.

I will ask someone to look here that specializes in this situation. Give them a day or two to reply.

Hello, lets have a look at the MBR of the drive.
I'll move this topic to a more appropriate forum.

Try this please. You will need a USB drive.

Download GETxPUD.exe to the desktop of your clean computer
  • Run GETxPUD.exe
  • A new folder will appear on the desktop.
  • Open the GETxPUD folder and click on the get&burn.bat
  • The program will download xpud_0.9.2.iso, and upon finished will open BurnCDCC ready to burn the image.
  • Click on Start and follow the prompts to burn the image to a CD.
  • Remove the USB & CD and insert it in the sick computer
  • Boot the Sick computer with the CD you just burned
  • The computer must be set to boot from the CD
  • Gently tap F12 and choose to boot from the CD
  • Follow the prompts
  • A Welcome to xPUD screen will appear
  • Press File
  • Expand mnt
  • sda1,2...usually corresponds to your HDD
  • sdb1 is likely your USB
  • Click on the folder that represents your USB drive (sdb1 ?)
  • Press Tool at the top
  • Choose Open Terminal
  • Type the following and press enter:

    dd if=/dev/sda of=mbr.bin bs=512 count=1

  • Press Enter
  • After it has finished a file will be located on your USB drive named mbr.bin
  • Remove the USB drive and insert it back in your working computer and navigate to mbr.bin, zip it up and attach it to your next reply.

This will allow me to have a look at the MasterBootRecord of your drive and see if it is infected.

regards, Elise

Thanks boopme. =)

Elise-- I've followed your steps up to the "A Welcome to xPUD screen will appear" bullet point.. but nothing appears except a blank yellow screen with a faded blue border. Did I miss something?
